iflibdd — Device Dependent Configuration Functions
Contents
Functions
The above named functions are device dependent configuration functions. These routines are registered
with iflib by the driver and are called from the corresponding iflib function to configure device
specific functions and registers.
DeviceDependentFunctionsSoftQueueSetupandTeardownifdi_tx_queues_alloc()
Mandatory function that is called during iflib_attach to allocate transmit queues. vaddrs and
paddrs are arrays of virtual and physical addresses respectively of the hardware transmit queues.
ntxqs is the number of queues per qset. ntxqsets is the number of qsets.
ifdi_rx_queues_alloc()
Mandatory function that is called during iflib_attach to allocate receive queues. vaddrs and
paddrs are arrays of virtual and physical addresses respectively of the hardware receive queues.
nrxqs is the number of queues per qset. nrxqsets is the number of qsets.
ifdi_queues_free()
Mandatory function that frees the allocated queues and associated transmit buffers.
ifdi_txq_setup()
Optional function for each transmit queue that handles device specific initialization.
ifdi_rxq_setup()
Optional function for each receive queue that handles device specific initialization.
DeviceSetupandTeardownifdi_attach_pre()
Mandatory function implemented by the driver to perform any attach logic that procedes interrupt
and queue allocation, queue setup, and interrupt assignment.
ifdi_attach_post()
Mandatory function implemented by the driver to perform any attach logic that occurs after
ifdi_attach_pre, and iflib's queue setup and MSI/MSIX(X) or legacy interrupt assignment.
ifdi_detach()
Mandatory function that frees any resources allocated by the driver in ifdi_attach_pre and
ifdi_attach_post.
ifdi_vlan_register()
Optional function called by the VLAN config eventhandler. vtag is the new VLAN tag.
ifdi_vlan_unregister()
Optional function called by the VLAN unconfig eventhandler.
ifdi_suspend()
Optional function that suspends the driver.
ifdi_resume()
Optional function that resumes a driver.
DeviceConfigurationFunctionsifdi_init()
Mandatory function that will initialize and bring up the hardware. For example, it will reset the
chip and enable the receiver unit. It should mark the interface running, but not active (
IFF_DRV_RUNNING, ~IIF_DRV_OACTIVE ).
ifdi_stop()
Mandatory function that should disable all traffic on the interface by issuing a global reset on
the MAC and deallocating the TX and RX buffers.
ifdi_multi_set()
Programs the interfaces multicast addresses
ifdi_media_status()
Media Ioctl Callback. Function is called whenever the user queries the status of the interface
using ifconfig(8). The driver sets the appropriate link type and speed in ifmr->ifm_active.
ifdi_mtu_set()
Sets the mtu interface to the value of the second function parameter mtu.
ifdi_media_change()
Function is called when the user changes speed/duplex using the media/mediaopt option with
ifconfig(8).
ifdi_promisc_set()
Enables or disables promisc settings depending upon the flags value. flags contains the
interface's ifnet(9) flags.
ifdi_get_counter()
Returns the value for counter cnt depending upon counter type.
ifdi_update_admin_status()
Sets the link_up state to TRUE or FALSE depending upon the OS link state. A real check of the
hardware only happens with a link interrupt.
ifdi_media_set()
Need to define
InterruptEnable/Disableifdi_intr_enable()
Mandatory function that enables all interrupts.
ifdi_intr_disable()
Mandatory function that disables all interrupts.
ifdi_queue_intr_enable()
Mandatory function that enables interrupts on queue qid.
iov_init()
Initialize num_vfs VFs.
io_uninit()
Tear down the context for all VFs.
ifdi_vflr_handle()
Handle any VFs that have reset themselves via a Function Level Reset (FLR).
ifdi_vf_add()
Set parameters in params in VF vfnum.
ServiceRoutinesifdi_timer()
Optional timer routine that will be run every 500ms.
ifdi_watchdog_reset()
Optional function to run when a transmit queue is hung.
AdditionalFunctionsifdi_led_func()
ifdi_sysctl_int_delay()
ifdi_i2c_req()
